As far as known, larvae, pupae and mine are identical to those of
I sequensi (= I. populi) - almost round, brown to brownish black, upper
surface, very opaque blotch, about 1 cm in diameter, without an
initial corridor. Upper epidermis leathery in colour. Often several
mines in a leaf. All frass as a tar-like film on the floor of the
mine (Bladmineerders van Europa).
Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).
Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sheaths (see examples).
Pupation in the mine; pupa not in a cocoon.
